creating alias for sendmail -> mhonarc

Hi...
Since I can't seem to find this documented anywhere, and for some
reason I can't get it to work...
What do I have to put in /etc/aliases in order that I can subscribe
to a mailing list as 'the alias' and have mail go there to be auto-archived?
Assuming that this is possible, of course...
I've tried:
tests: "|/loc/bin/mhonarc -add -outdir /loc/www/lists/tests"
But I get an error back from mail concerning 'unknown mailer error'...
Thanks...
